10. Atletico Madrid
Transfers - 331
Amount spent - £1.23bn
The Diego Simeone era has coincided with some serious spending. Joao Felix alone cost the club £113m, with Thomas Lemar signed for £63m as well.
Transfers - 369
Amount spent - £1.35bn
Much of Jurgen Klopp's current starting XI was signed for £30m+, so it's no surprise to see Liverpool in ninth.
8. Paris Saint-Germain
Transfers - 266
Amount spent - £1.41bn
The only surprise here is that PSG aren't higher up on this list, especially given the fact that Neymar and Kylian Mbappe cost a combined total of over £300m.
7. Inter Milan
Transfers - 790
Amount spent - £1.44bn
Inter ahead of PSG?! A bit of a shock, until you see that the Italian outfit have made over 500 more transfers than their French counterparts...
6. Manchester United
Transfers - 316
Amount spent - £1.62bn
The list of United players signed for huge money this century is enormous. It's surprising that the acquisitions of Paul Pogba, Harry Maguire, Bruno Fernandes and more haven't seen United break the top five.
Transfers - 761
Amount spent - £1.73bn
A huge volume of transfers once again, combined with Cristiano Ronaldo, Gonzalo Higuain and Matthijs de Ligt costing £70m+ sees Juve squeeze ahead of United.
4. Manchester City
Transfers - 409
Amount spent - £1.86bn
Sheikh Mansour's millions have seen City sign a whopping spend more than £40m on 13 players, which is pretty outrageous.
Transfers - 195
Amount spent - £1.87bn
Philippe Coutinho, Ousmane Dembele and Antoine Griezmann were all signed for over £100m, so is it any surprise to see the Blaugrana in the top three?
2. Real Madrid
Transfers - 201
Amount spent - £1.95bn
Spending close to 20 years signing 'Galacticos' was always going to chalk up a sizeable bill. Like City, Los Blancos have spent over £40m on 13 different players.
Transfers - 471
Amount spent - £1.96bn
The Blues nick top spot by a whisker. Roman Abramovich has pumped some serious cash into the club this century, with the Blues spending £30m+ on a player 20 times.
The money in football really is ridiculous, isn't it?
